Boxspring Bed Frame Double/Full Size Temperature-Regulating Mattresses Breathable Mattresses Mattress and Bed Accessories
A temperature-regulating mattress works to keep you at a comfortable, balanced temperature all night and all year — not just cooling you down, but adapting as your body and the seasons change so you don't wake up too hot or too cold. These mattresses use heat-responsive and breathable materials — phase-change covers, gel and graphite foams, Tencel and natural fibres, and airflow-promoting coils — to absorb and release warmth as needed. It's ideal if you run hot and cold, share a bed with a partner who sleeps at a different temperature, or just want consistent comfort through every season. You'll find temperature-regulating builds across every brand — Sealy, Serta, Beautyrest, iComfort, Tempur-Pedic, Chirofoam and our own NM line. Sleep hot specifically? See our cooling mattresses. Every mattress includes a 365-night sleep trial and free delivery across Canada. • What it does: holds a balanced, neutral temperature — adapts so you're not too hot or too cold • How it works: phase-change covers, gel & graphite foams, Tencel/natural fibres and breathable coil airflow • Best for: people who run hot and cold, couples with different sleep temperatures, and year-round comfort • Cooling vs regulating: cooling sleeps cold (for hot sleepers); regulating holds a steady, balanced temp • Across every brand and firmness • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
Breathable mattresses are built to move air, not trap it. Through ventilated and open-cell foams, breathable knit and Tencel covers, and pocket-coil airflow, they let heat and moisture escape instead of building up under you — so your sleep surface stays fresher, drier and more comfortable through the night. It's a great fit if you sweat at night, live in a humid climate, or just don't like that stuffy, sunk-in feel. You'll find breathable builds across every brand — Sealy, Serta, Beautyrest, iComfort, Tempur-Pedic, Chirofoam and our own NM line — in foam, hybrid and pocket-coil. Sleep especially hot? See our cooling mattresses for active heat-wicking. Every mattress includes a 365-night sleep trial and free delivery across Canada. • What it means: airflow-focused builds that let heat and moisture escape instead of trapping them • How it works: ventilated/open-cell foams, breathable knit & Tencel covers, pocket-coil airflow • The benefit: a fresher, drier, less stuffy sleep surface • Best for: sweaty sleepers, humid climates, or anyone who dislikes a sunk-in, stuffy feel • Sleep hot? See cooling mattresses; want a steady temp? See temperature-regulating • Across every brand and firmness • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
The bed you sleep on is a system, and the pieces around the mattress decide how well it performs. National Mattress carries pillows matched to how you sleep, mattress protectors that keep spills and body oils out of the comfort layers, bedding and sheets, mattress toppers, and the support that goes underneath: box springs, bed frames, adjustable bases, and bedroom essentials such as headboards and platform bedframes. Choosing well is mostly a matter of matching each piece to your sleep position, your mattress height, and the support your mattress needs to sit flat.
How to Choose Bedding and Sleep Accessories
A bed is a system, and the pieces around the mattress decide how much of its comfort you actually feel. Start with the pillow, because it sets the angle of your neck and is the easiest thing to get wrong. Side sleepers need a high loft to fill the gap between ear and shoulder, back sleepers a medium loft that supports the curve of the neck without pushing the chin forward, and stomach sleepers the thinnest pillow they can tolerate. Fill then decides feel: memory foam, whether one moulded piece or granulated and loose, softens under body heat and holds the shape it takes; latex pushes back sooner and reads firmer and less enclosing at the same firmness label; feather can be punched into any shape and needs re-fluffing to keep it; and fiberfill sits lightest and washes most easily.
Below the sheets the job changes from comfort to protection and support. A mattress protector is a barrier against spills, sweat and skin oils, all of which reach the foam long before a stain shows. When you buy sheets, check the fitted pocket depth against your mattress height plus any topper, because a shallow pocket pops off the corners. Underneath, a mattress only performs on even, continuous support: a sound box spring, a bed frame with closely spaced slats, or an adjustable base if you want to raise the head and legs. Bedroom essentials such as headboards and platform bedframes finish the room.
Pillow Loft by Position
Loft, not softness, is the real decision. Match pillow height to the gap your sleep position leaves, then pick a fill that holds that height.
What a Protector Blocks
Liquid, perspiration and skin oils reach the comfort layers long before a stain shows, and foam does not wash. A thin knit faced laminate blocks all three and is close to unnoticeable; a quilted or padded protector softens the surface slightly.
Sheet Pocket Depth
Measure the mattress from top seam to bottom seam, add any topper, then buy a fitted sheet with a deeper pocket than that total.
Support Underneath
Foam and pocket coil beds need even support across the whole surface. Closely spaced slats, a sound box spring or an adjustable base all provide it.
